The fix for the fix breaks cameras, Explorer, and booting

The January preview update, intended to fix the chaos from KB5073455, introduced its own fresh set of regressions. Integrated laptop cameras stopped working entirely. Explorer.exe crashed, taking the taskbar and Start menu with it into the void. Brief black screens appeared. Some systems needed recovery mode to boot. Storage settings suddenly demanded admin permissions for no reason. Temporary Files cleanup broke. It was the fix that needed a fix that needed a fix — a recursive loop of incompetence that wouldn’t resolve until February’s Patch Tuesday arrived to break new things.
